1) Flies of all sorts - Landing on things and spreading their poop loving filth. Fruit flies really gross me out cause they swarm in hoards.
2) Fleas - Disgusting, unsanitary, germ spreading, icky villians of doom.
3) Mosquitoes - They terrify me. If a fly and a flea got it on and had a baby it would be a mosquito. It's the worst creature in the universe.
4) Ticks - Sneaky little bastards of burrowing disease.
That about sums up my list of foulness. Of course there are others that thoroughly give me the heeby-jeebies but these sickos top my list. What are you most grossed out or scared by?
Note: While looking for images for this post I actually had to stop a few times because I was so grossed out. With my weak pregnancy stomach I got thisclose to vomiting. Eew!
